How is Jesus the same as the God of the old testament?

When I call myself a Christian it means I follow the teachings and attitudes of Jesus. The problem is that Jesus teachings directly contradict the law of the old testament. People all around the world say they are Christian but do they follow Jesus or are they just religious. In northern Ireland not that long ago protestants and catholics were murdering each other in the name of Christ. These people claim to be Christians but their action show they are children of Satan. I want to know how sane rational individuals who claim to love Jesus can believe HE is the same God as the old testament god. The God of the old testament was clearly hypocritical. He said thou shalt not murder. He said thou shalt not commit adultery. Then he said if someone commits adultery thou shalt brutally murder them by beating them to death with stones. this god is not Christ he is antichrist. He said if someone is gay they shall be killed. He told the jews to commit m genocide over and over again. he instructed the jews to kill women and little children and spare no life. Jesus would never do these things. Jesus would never command His people to commit atrocities. The Old testament clearly teaches bigotry of every kind. the Old Testament teaches that women are to be dominated and mastered by men. The Old testament law clearly stipulates that female laborers should be paid less than male laborers. The Old testament teaches the oppression of women very much like Islam teaches that women are merely the property of men. The Old testament treats women the same way as radical Islamic terrorists treat women. I was taught that as a child that the Bible is the perfect word of God and contains no errors. I was taught that everyone who wrote, translated, and compiled the books of the bible were all perfectly inspired of the Holy Spirit and they made no mistakes. When I ask pastors and bible teachers exactly who these inspired men were they have no idea they just accept the umption that they were perfectly inspired. The problem with this umption is that the New Testament teaches that everyone who accepts Jesus as their savior is filled with the Holy Spirit unfortunately these Holy spirit filled christians make mistakes on a daily bases which proves that even people inspired by the Holy Spirit constantly make errors and commit sin. This means that even if everyone who put together the bible was inspired of the Holy Spirit they would still make mistakes and malign the message. Humans cannot write a perfect book. Not even with the empowerment of the Holy Spirit. It is impossible. My pastor is inspired of the Holy spirit but he still sin and makes mistakes and has his own biases and prejudices and so did the people who wrote the bible. The only books of the Bible I base my faith on are the ones about Jesus. I have seen what happens to Christians who read the Old Testament too much they become a bunch of hyper religious, judgmental, angry, hateful, hypocritical, bigoted pharisees. These christians would stone people to death if they could get away with it but they can't so they stone people figuratively by judging them and damning them to hell publicly. they become just like the pharisees who Jesus could not tolerate. The new Testament ways God is love. Love does not stone people to death. Love does not commit or incite genocide and the murder of women and children. Love is not a hypocrite. Love does not know how to kill. the old testament says to "Fear God" The New Testament says perfect love casts out all fear. the old testament god wants you to fear because he is really satan in disguise as god. The new testament God Jesus Christ casts out all fear. he tells you "I love you" he says"I forgive you". The only sin Jesus ever said was unforgivable was the sin of not forgiving others. Jesus clearly said if you don't forgive others you will not be forgiven. The only laws Jesus commanded us to follow are 1) Love the Lord your God with all your heart and mind and strength and (2) Love your neighbor as yourself. this is exactly the opposite of the Old Testament God who gave people an unbearable burden of thousands of excessive laws they could never possibly follow. Jesus teaches LOVE the god of the old testament only teaches legalism which creates pharisees who are killers like their father the devil. I realize having this view makes me an apostate heretic. but I would rather go to hell for loving people than go to heaven for judging people. I would rather go to hell for the right reason than go to heaven for the wrong reason. Who wants to go to a heaven full of Pharisees and legalistic haters. I think the god many so called christians worship is really just satan in disguise. After all hasn't satan always set himself up as God. I'm sick of so called Christians who always think everyone else's sin is worse than their own. They see a s
